Condition: New
Note: price and availability are subject to change without prior notice
The ASUS 40W 2.5mm Laptop Adaptor supplies 19V at 2.1A through a slim 2.5x0.7mm pin, and Mascom International stocks it at KSh 1,600, ready for collection or delivery today. It is a brand new replacement adaptor for ASUS laptops, made for ASUS Eee PC netbooks and similar small ASUS models that use the same tiny pin. Each ASUS 40W 2.5mm Laptop Adaptor pairs a compact brick and attached DC cable with a detachable mains cord. Find it at our shop on the first floor of Old Mutual Building, Room 4, Kimathi Street, in the heart of the Nairobi CBD.
Designed for owners who still rely on a small ASUS netbook, the ASUS 40W 2.5mm Laptop Adaptor keeps those light machines working for typing, email and simple record keeping. Plenty of these netbooks are still at work in school offices, small shops and family homes. Their original chargers are now hard to find, and the thin pin bends or snaps easily. Without a charger, a netbook that still works ends up forgotten in a drawer. This adaptor restores the correct 19V supply, so a shop owner in Thika can track stock again and a child can return to typing practice.
Where most Nairobi electronics shops have stopped stocking chargers for older netbooks, Mascom International keeps the ASUS 40W 2.5mm Laptop Adaptor on the shelf. Buyers throughout Kenya report that finding the right pin was the hardest part of reviving an old Eee PC. A dedicated plug also fits more firmly than a universal charger's swap-on tip, which matters on a pin this thin. Send your netbook model or a photo of the old charger's label on WhatsApp, and we will confirm the match. Then visit our Kimathi Street shop to test the ASUS 40W 2.5mm Laptop Adaptor on your netbook, or order with pay-on-arrival delivery.
Common Questions About the ASUS 40W 2.5mm Laptop Adaptor
How much is the ASUS 40W 2.5mm Laptop Adaptor in Kenya?
The ASUS 40W 2.5mm Laptop Adaptor sells for KSh 1,600 brand new at Mascom International, Kimathi Street, Nairobi CBD. That price includes the adaptor brick with its attached thin-pin cable, a detachable mains cord and a 6-month warranty. You can pay on arrival, in cash or by M-Pesa, anywhere in Kenya. The ASUS 33W 4.0mm Laptop Adaptor costs KSh 1,800, which is KSh 200 more, but it uses a larger plug and cannot replace this one. Choose by plug size and label, never by price alone.
Will the ASUS 40W 2.5mm Laptop Adaptor work with my Eee PC netbook?
The ASUS 40W 2.5mm Laptop Adaptor works with ASUS Eee PC netbooks whose chargers read 19V and 2.1A, with a 2.5x0.7mm pin. Many 10-inch Eee PC models used this combination. The earliest Eee PC netbooks ran on a lower voltage, so they need a different charger. Check the label on your old adaptor or under the netbook before you buy. If the label has worn away, send the model number from the netbook's base on WhatsApp, and Mascom International will confirm the fit within your chat.
What does 2.5x0.7mm mean on the ASUS 40W 2.5mm Laptop Adaptor?
The 2.5x0.7mm figure on the ASUS 40W 2.5mm Laptop Adaptor describes a plug 2.5mm wide outside, with a 0.7mm hole in the centre. It is a tiny barrel plug, roughly the thickness of a matchstick. A larger plug will not enter the socket at all, while a universal tip that is nearly right can wobble and lose contact. The small pin is also fragile. Push it in straight, pull it out by the head, and never lever it sideways while the netbook rests on your lap.
How does the ASUS 40W 2.5mm Laptop Adaptor compare with the ASUS 33W 4.0mm Laptop Adaptor?
The ASUS 40W 2.5mm Laptop Adaptor and the ASUS 33W 4.0mm Laptop Adaptor both run at 19V, but their plugs differ, so they are not interchangeable. This adaptor supplies up to 2.1A through a 2.5x0.7mm pin and costs KSh 1,600. The 33W model supplies up to 1.75A through a 4.0x1.35mm plug and costs KSh 1,800. Pick this one for Eee PC netbooks with a tiny round socket. Pick the 33W model for later small VivoBook and E-series laptops with a wider socket.
Is the ASUS 40W 2.5mm Laptop Adaptor safe during KPLC outages and voltage swings?
The ASUS 40W 2.5mm Laptop Adaptor comes through ordinary KPLC outages safely; the netbook switches to its battery, if the battery still holds charge. Damage usually comes from the surge when supply returns, or from lightning on the line. Connect the mains cord through a surge protector or UPS, not straight into the wall socket. Older netbook batteries often hold little charge, so this adaptor may be your netbook's main power source, which makes protecting it more important. Unplug it fully during heavy storms.
Is it worth buying a new adaptor for an old Eee PC?
Yes, if the Eee PC still boots and you need it for light work such as typing, email or a stock spreadsheet. At KSh 1,600, the ASUS 40W 2.5mm Laptop Adaptor costs far less than any replacement laptop, even a used one. Netbooks handle documents, basic browsing and offline records well, though heavy websites and video calls feel slow on their small processors. If your netbook also needs a new battery, screen and keyboard, put that money toward a newer laptop instead. Mascom International can advise on both paths in store.
Who is the ASUS 40W 2.5mm Laptop Adaptor for, and who should look elsewhere?
The ASUS 40W 2.5mm Laptop Adaptor is for owners of ASUS Eee PC netbooks and similar small ASUS models with a 19V 2.1A label and a tiny 2.5x0.7mm socket. It suits small businesses, school offices and families keeping an older netbook in service. Look elsewhere if your ASUS has a wider round socket or charges by USB-C. For the 4.0mm socket, Mascom International stocks the ASUS 33W 4.0mm Laptop Adaptor, the ASUS 45W 4.0mm Laptop Adaptor and the ASUS 65W 4.0mm Laptop Adaptor; match the wattage to your label.
Can I carry the ASUS 40W 2.5mm Laptop Adaptor when I travel?
Yes, the ASUS 40W 2.5mm Laptop Adaptor is light and compact, and its detachable mains cord makes it easy to pack for trips upcountry. The thin pin is the part to protect. On long matatu journeys, keep the plug end in a small pouch or side pocket so heavy items cannot bend it. Coil the cable loosely instead of wrapping it tightly around the brick. Dust can collect inside the netbook's tiny socket, so blow it out gently before plugging in after a dusty trip.
Technical Specifications
Core Function
- 19V DC output — the voltage later ASUS Eee PC netbooks expect, delivered as steady direct current to their charging circuit.
- Up to 2.1A current — enough for a netbook to run and refill its battery together during typing, browsing and spreadsheet work.
- 40W rated power — 19 volts multiplied by 2.1 amps comes to roughly 40 watts, matching the rating on compatible netbook chargers.
- Wall power conversion — turns the socket's alternating current into the low-voltage direct current a netbook can use without harm.
- Use while charging — keep working on mains power as the battery fills, useful for netbooks whose ageing batteries hold little charge.
- Detachable mains lead — the brick connects to any ordinary wall socket or surge strip through its separate power cord.
Compatibility
- ASUS Eee PC netbooks rated 19V 2.1A — many 10-inch Eee PC models carry this rating and thin pin; check your label first.
- Similar small ASUS models with a 2.5x0.7mm socket — any ASUS machine whose label and plug size match these figures exactly.
- Label check — the old charger or the netbook's base should read 19V and 2.1A; send a photo on WhatsApp if unsure.
- Not for the earliest Eee PC models — those first netbooks ran on a lower voltage and need a different charger altogether.
- Not for 4.0mm ASUS sockets — VivoBook and E-series laptops with a wider round socket need the 33W, 45W or 65W 4.0mm adaptors.
- Not for USB-C ASUS laptops — an oval USB-C port needs a USB-C charger rather than any round barrel plug.
Build
- 2.5x0.7mm barrel plug — 2.5mm outer diameter with a 0.7mm centre hole, a slender round connector suited to slim netbook bodies.
- Attached DC lead — the thin plug is fixed permanently, avoiding the loose fit of universal chargers that rely on swap-on tips.
- Two-piece layout — brick and attached DC lead plus a separate mains cord, so a damaged mains cord can be replaced by itself.
- Small brick — fits beside the netbook in a sleeve, easy to carry to school, the shop counter or a client visit.
- Replacement adaptor for ASUS laptops — brand new stock built to the same voltage, current and plug size as the original.
- Mains plug type — Kenyan sockets take 3-pin UK-style plugs, so confirm the plug supplied on WhatsApp before dispatch.
Inclusions
- Adaptor brick with attached DC cable — the charger itself, with the 2.5x0.7mm pin fixed to the cable end.
- Detachable mains power cord — links the brick to the wall and unplugs for packing in a bag.
- 6-month warranty — manufacturing defects under normal use, with claims handled at the Mascom International service desk in Nairobi CBD.
- Fit confirmation — send your netbook model or a label photo on WhatsApp, and the team checks the match before you pay.
- Pay-on-arrival delivery — pay only when the parcel reaches you, with same-day delivery within Nairobi and its environs.
- In-store testing — bring your netbook to the Kimathi Street counter and plug the adaptor in before paying, so you leave knowing it charges.
- Brand new condition — every unit leaves the shelf unused, with a clean cable and plug rather than a worn second-hand charger of unknown history.
Package Contents
Inside the box you get the ASUS 40W 2.5mm Laptop Adaptor brick with its DC cable and 2.5x0.7mm pin already attached, and a detachable mains power cord. Together they power a compatible netbook and charge its battery straight from a wall socket. There are no adapter tips to sort through, since the pin is fixed at the correct size. Because Kenya uses 3-pin UK-style sockets, message us on WhatsApp to confirm the mains plug type before your order leaves the shop.
